CHRISTIAN KoHLER, or GALENA, ILLINOIS.

7 Letters Patent No. 84,700, dated December 8,1868. Q

INIPROVED CAR-COUPLING.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, Orrnrsrmrr Konnnn, of the city of Galena, in the county of J o Daviess, and State of Illinois, have invented a new and useful Impovernent for Coupling- Railway-Oars, which I entitle Kohlers Self-Oar-Goupler; and I do 'hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which' Figure 1 is aperspective view.

Figure 2, a half-section inside view when the cars are coupled.

Figure 3, the separate parts, and.also a half section inside view, with all the parts combined, when the car is uncoupled.

The different parts are represented on the drawings as follows:

a is the-lever or handle.

b is the hole for rope or string fastening.

c is the coupling-loop.

d is the car-header.

e is the fastening for the lever or handle.

f are the rests for the lever or handle.

g is the part fastened on the car.

h is the coupling-pin, fastened won the lever or handle, so as to swing on it.

'i is the hollow space for couplingrloop to move in.

j is'the hollow space for coupling-pin to move in.

k is thesteel spring to force the coupling-pin back to a perpendicular position.

l is the spring fastening.

1 m is the fastening of coupling-pin to the handle or ever.

h, in fig. 3, is the side view of the coupling-pin.

H, in fig. 3, is the back view of the coupling-pin.

k, in fig. 3, is the top view of the spring.

K, in fig. 3, is the side view of the spring.

D, in fig. 3, is the boxwithout the header or lever, in which the coupling-pin and loop work.

The spring is made of steel, of sufiicient length and strength to throw back the coupling-pin to its place. Allthe other materials may be made of wrought or cast-iron,'0r both.

The hollow space for the coupling-loop may be of the size now inuse, and the hollow space for the coupling-pin should be of such size as to let the pin swing free in it.

Thework should be made four times as large as the size of the same in the accompanying drawings.

The operation of this improvement is as follows:

Two cars coming together, the lever or handle being down, as in figs. 1 and'2, the coupling-loop a being on one of the cars, the .loop is pressed forward against the coupling-pin h, which it presses back against the spring It, raising the spring, when the loop passes the lower end of the pin, and then-the spring throws the pin back to a perpendicular position against the inside of the header. Thepin is then-through the loop, and the car is coupled. To uncouple it, the lever or handle is raised, as in fig. 3.

The lever maybe raised by hand direct, or by fastening a rope or string at the rope-hole b, and leading the rope into the car, and pulling upon it.

To place the lever back in its place, as in figs. l and v 2, a spring might be attached to the car-header, so as to strike the lever when it is raised, and throw it back. This to be of suf icient size and strength for that purpose.

I do not claim, as my invention, the car-header or coupling-loop. I I What I do claim asmy invention, and desire to secure by Letters Patent, is-

The combination of the lever w, pivoted pin h, with a bufi'er-head, which has cavities i and j therein, when constructed and a ranged to operate in connection with a spring, k, substantially as described, as and for the purpose specified.
